Have people found a way to hack MarioKart DS? I hope not, it really bothers me how online games are plagued by hackers now. What makes me think this is occasionally when I play another persons kart will act worse than if it was just lagging. Every time they run into a wall they immediately disappear and reappear a good distance ahead of where they are (about as far as you can see on the top screen, slightly less). They also "blink" in and out like this as soon as I get ahead of them. Yet . . . at no other time does this happen. Only when they hit a wall or I pass them. If it was simple lag, you'd think it would happen at other times. I also went against someone who seemed way faster than he was suppose to be. I've played against people with his character/kart before, and he was noticeably faster. I was on a straight run, they had no items and did not use my wake. They litterally went from one wall to another, HITTING the walls, back and forth zigzagging the whole time, yet he got so far ahead on a single straight that I couldn't see him anymore, when he started behind me. I hope this isn't hacking, and I hope hacking isn't commonplace. Since Nintendo makes a set between your card/DS, if it is you would hope they could find a way to kick those people off.
